Abstract
A spark spectroscopic high-pressure gas analyzer including a spark chamber, having a pair of electrodes, for receiving a sample of the pressurized gas to be analyzed. A voltage is provided across the electrodes for generating a spark in the pressurized gas sample. A selected wavelength band of radiation emitted from the spark discharge in the pressurized gas corresponding to a component to be sensed in the gas is detected. The intensity of the emission in the wavelength band is integrated during the afterglow time interval of the spark emission and a signal representative of the integrated intensity of the emission in the selected narrow wavelength band is employed to determine the proportion of the component in the gas.
